Identify the null hypothesis, alternative hypothesis, test statistic, conclusion about thenull hypothesis, and final conclusion that addresses the original claim.The health of employees is monitored by periodically weighing them in. A sample of54 employees has a mean weight of 183.9 lb. Assuming that o is known to be 121.2Ib, use a 0.10 significance level to test the claim that the population mean of all suchemployees weights is less than 200 lb.
